摘要
The levels of plasma nitric oxide (NO), endothelin 1 (ET 1) and ALT in the patients with chronic hepatitis B and active cirrhosis and the correlation among them were observed and analyzed. NO 3 ˉ was restored by using cadmium column assay and NO 2 ˉ measured by heavy nitrogen assay. The primitive NO 3 ˉ and total restored NO 2 ˉ(NO 3 ˉ/ NO 2 ˉ) in plasma of the patients with chronic hepatitis and cirrhosis. Plasma ET 1 and ALT levels were determined by using radioimmunological assay and Lai's assay, respectively. Compared with normal control group, the plasma levels of NO 2 ˉ/NO 3 ˉ and ET 1 in the patients with chronic active hepatitis and active cirrhosis were significantly increased ( P <0.05-0.01). There was a positive correlation between NO and ALT, and ET 1 and ALT in the patients with chronic active hepatitis and active cirrhosis respectively. It was suggested that elevation of both NO and ET 1 levels were closely related with injury severity of liver function.
